Rust protection distribution line isolating switch, comprise base, moving contact, fixed contact, two post insulators are fixed with binding post, fixed contact respectively, it is characterized in that: inside and outside two moving contact dististyle A that described moving contact A holds are fixed by spacing steel bushing and (should prevent because the too small conjunction of moving contact spacing is not gone up, making the moving contact dististyle A of this end when closing a switch again, can more closely block fixed contact A); Inside and outside two moving contact dististyle B that moving contact B holds are placed in fixed contact B both sides, and all hinged with fixed contact B; The moving contact dististyle at inside and outside moving contact A, B two ends is fixedly connected with by spring steel plate respectively; Moving contact A end is fixed with connector, and this connector connects the binding post at fixed contact B place by flexible conductor.
Further:
Described flexible conductor is one, arranges in outside or inner side; Namely moving contact A holds outside or inner side to be fixed with connector, and this connector connects outside or the inner side of the binding post at fixed contact B place by flexible conductor.
Described flexible conductor is two (meeting the needs of heavy current disconnecting switches), and one or both sides are arranged; Described side is arranged, and namely refers to: moving contact A holds outside or inner side to be fixed with two connectors, and these two connectors all connect outside or the inner side of the binding post at fixed contact B place by flexible conductor; Described both sides are arranged, and namely refer to: moving contact A holds outside to be fixed with connector, and this connector connects the outside of the binding post at fixed contact B place by flexible conductor; Moving contact A holds inner side to be fixed with connector, and this connector is connected inside the binding post at fixed contact B place by flexible conductor.
Described moving contact dististyle A place is provided with magnet, its structure is: magnet upper end linking springs, and spring upper end is fixed on moving contact dististyle along place by nut.
Described two moving contact dististyle B and fixed contact B is hinged is realized by plastic bearing; That is: in fixed contact B installing plastic seal bearing and moving contact dististyle B hinged.
Described flexible conductor is annealed copper wire.
Isolating switch described in the utility model, movable part is connected by original bolt, changes sealed plastic bearing-transmission into, is electrically connected by flexible conductor; Dynamic/static contact, by original spring compression, changes leaf spring into and compresses.These improve and form following beneficial effect:
1, steel spring plate area is larger, can extend well and bear the corrosion time limit; Steel spring plate can clamp the dynamic and static contact of isolating switch better, reduces contact resistance.Connect conduction by original copper coin and use annealed copper wire connection instead, ensure isolating switch conductivity well, isolating switch divides, co-bit is put to utilize annealed copper wire connection not affect.
2, former isolating switch connecting lever place connects and is connected compression with stainless steel bolt with leaf spring, connecting lever place is increased dress sealed plastic bearing, under any circumstance can not become rusty and extremely can ensure the flexibility at connecting lever place very well.
3, slip-off preventing: adopt Neodymium-Iron-Boron super magnet, fine adhesive moving contact and fixed contact, prevents the unexpected moving contact that causes from departing from fixed contact.
The beneficial effects of the utility model are: generally, and the utility model structure is simple, and do not affect the outward appearance of isolating switch, lightweight, the life-span is long, easy for installation, attractive in appearance, durable.Trial run shows, generally, can running the more than ten years, that rust can not occur is dead, thus avoids drawing, not closing the generation that isolating switch affects distribution line operation troubles.
In order to make those skilled in the art person understand the utility model scheme better, and enable above-mentioned purpose of the present utility model, feature and advantage become apparent more, below in conjunction with embodiment, the utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is the structure chart of the utility model isolating switch,
Fig. 2 is that the utility model installs rear vertical view,
Fig. 3 is the utility model partial enlarged drawing.
In figure: 1 is post insulator, 2 is binding post, and 3 is fixed contact A, 4 is magnet, and 5 is spring, and 6 is moving contact dististyle A, 61 is moving contact dististyle edge, and 7 is connector, and 8 is steel spring plate, 9 is flexible conductor, and 10 is moving contact dististyle B, and 11 is plastic bearing, 12 is fixed contact B, 13 bases, and 14 is spacing steel bushing, 15 is nut, and 16 is bolt.
Embodiment
As shown in Figure 1, Figure 2, Figure 3 shows.
Rust protection distribution line isolating switch, comprise base 13, moving contact, fixed contact, two post insulators 1 are fixed with respectively binding post 2, fixed contact 3, inside and outside two moving contact dististyle A6 that described moving contact A holds are by spacing steel bushing 14 fixing (see Fig. 2), making the moving contact dististyle A6 of this end when closing a switch, guaranteeing can more closely block fixed contact A3; Inside and outside two moving contact dististyle B10 that moving contact B holds are placed in fixed contact B12 both sides, and all hinged with fixed contact B12; Inside and outside moving contact dististyle A, B are fixedly connected with (spring steel plate 8 is fixed with inside and outside moving contact A, B by bolt 16) by spring steel plate 8 respectively; Moving contact A end is fixed with connector 7, and this connector 7 generally adopts copper by flexible conductor 9() connect the binding post 2 at fixed contact B place.
Further:
At moving contact dististyle A6 place, be provided with magnet: its structure is: magnet 4(Neodymium-Iron-Boron super magnet) upper end linking springs 5, moving contact dististyle is fixed on along 61 places (see Fig. 3) by nut 15 in spring 5 upper end.The edge that described moving contact dististyle is formed along 61 for the 90 degree of bendings of this moving contact plane.
Adopt spring be because: need very large strength when closing isolating switch, moving contact often closed a little a little.As adopted fixing dead Neodymium-Iron-Boron super magnet, can bend connecting rod, causes magnet positions to change, and can not hold the iron bolt on binding post 2 well.
Two moving contact dististyle B10 and fixed contact B12 are hinged to be realized by plastic bearing 11.
The feature of plastic bearing: (1) can under the special occasions of higher temperature steady operation (such as wet environment, akaline liquid).(2) good self-lubricating and anti-wear performance, without the need to grease up/oil.(3) without metallic pollution, Environmental Safety.(4) rigidity is large, and hardness is high, good springiness, and under high and low temperature, impact strength is high.(5) lightweight, non-corrosive, nonmagnetic, electric insulation.
Plastic bearing inner ring, outer ring, be high strength POM nylon plastic(s), and retainer is high performance resin, and centre is glass steel ball.Working temperature is from-60 DEG C ~ 100 DEG C, and surface strength is high and smooth, its good self-lubricating property and low coefficient of friction, is particularly suitable for the medium-term and long-term use of adverse circumstances in humidity or water, never corrosion.
The above; be only embodiment of the present utility model; but protection range of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the change that can expect easily or replacement, all should be encompassed within protection range of the present utility model.
